Hi, we adopted a female yorkie about 6 months ago and we wanted to add another to the family. Lillie is very active, but loves to snuggle as well. We have noticed that she tries to show dominance with another female yorkie. She lays on her and barks at her to try to get the other female yorkie to play. She does mark her spots outside, but not inside. I need some advice on adding another yorkie. Should we try for a male? I have heard that if two yorkies are going to fight, it will be 2 females. Any thoughts? Thanks so much!!
